Was running the pump 24hrs a day, but im back on the timer..Electric bill went from $385 to $509 within a month here in Dallas...I freaked out!!!!!!!!!!!!! I do have a two speed motor, but not sure if the slower speed is efficient enough....so ive backed off to running pool 12hrs a day...Hope it comes down a bit....IF NOT, then I at least have two more high bills to anticipate before September always seems to drastically decline..I believe the electric company just charges what they want..lol
